A court challenge to Proposition A, the earnings tax issue on the November ballot, has a September 17th hearing date. The city attorney for Kansas City, Galen Beaufort, filed the lawsuit, claiming that Prop A is unconstitutional and should be stricken from the ballot.

Prop A would require Kansas City and St. Louis to hold a referendum on the earnings tax, a referendum that must be held every five years. If voters reject the one percent levy on salaries and earnings in the two cities, the earnings tax would be phased out over a 10-year period.
